tfZ August 20, 1992 Mr. Brian Kooiker Permits, Compliance, and Protection Departn~ent of Environmental Conservation Agency of Natural Resources State of Vermont 103 South Main Street-The Annex Waterbury, VT 05671-0405

Subject:

NPDES unplanned discharge, August 14, 1992.

Reference:

NPDES Permit No. 3-1199, VT0000264.

Dear Mr. Kooiker:

This letter is written to document an incident which occurred at the Vermont Yankee Nuclear Power Station on August 14, 1992 which resulted in an unplanned release to the Connecticut River at Vernon of a limited amount of water slightly contaminated with radionuclides.

The incident was verbally reported to Ms Nancy Manley of the Agency on August 18th at 8:30 a.m. and earlier to Mr William Sherman, Vermont State Nuclear Engineer, on August 17th at 10:00 a.m.

A description of the event is attached. The incident is still under evaluation by Vermont Yankee personnel and will result in a Corrective Action Report.

Current radiological analyses show that limits established by the Nuclear Regulatory Commission have not been exceeded. The event will be reported in the semiannual Radiological Effluent Report.

In the event you should require further information, please do not hesitate to call.

Sincerely, Daniel J. Marx, Ph.D.

Environmental Scientist Attachment, VYNPC, 8/20/92.

Attachment, VYNPC, 8/20/92 Overflow of Condensate Demineralizer Backwash Receiving Tank On August 14, 1992 at approximately 1330, while backwashing the B condensate demineralizer and transferring the contents to the condensate demineralizer backwash tank, the electric pump which transfers the water from the tank to radwaste failed, resulting in the backwash receiving tank overflowing onto the floor. The water was radioactively contaminated and contained some resin material. The floor in the vicinity of the tank was flooded to a depth of approximately 1-2 inches.'%

Samples" taken in a nearby sump indicated the presence of radioactive Iodine and Tritium.

The sump pumps are designed to cycle if required by level so it is possible that some contaminated water was discharged to the river by way of the service water system (10,000 gpm) and then into the main circulating water system (360,000 gpm) before entering the Connecticut River.

The precise volume of contaminated water that may have been discharged to the river is estimated to be less than 15 gallons. Radiation monitors and samples at the point of discharge did not record any evidence of radioactivity and remained normal during the entire event.

Vermont Yankee personnel isolated the sump pumps and terminated the potential discharge at approximately 1430.

Based on radiological analysis of samples taken from the floor, sumps, and the discharge structure, and assuming bounding conditions, Vermont Yankee calculated that Technical Specifications and NRC 10CFR requirements and limits were not exceeded and the event was not reportable to the NRC. The calculated parameter values were also below Vermont Department of Health Radiological Health limits and the NPDES Permit limits.

The calculated values were based on the extremely conservative assumption that radioactive water was pumped out of the sumps and discharged through the normal flow path to the river continuously during the event. The calculation assumes dilution by the flow of the circulating water system (360,000 gpm) occurring concurrently with the discharge.

The actual volume of radioactive water discharged is estimated to be three orders of magnitude below the bounding calculated values, or less than 15 gallons. Connecticut River flow at the time of the incident was approximately 6000 cfs.

OPERATIONS DEPARTMENT MEMORANDUM TO:

S.Skibniowsky DATE:8/18/92 FROM:

J.T.Herron FILE:

SUBJECT:

Condensate spill On-8/14/92 R.

Gerdus and I

needed to evaluate if the notification requirements of 10CFR50.72 had been met which would require us to contact the NRC via the NRC red phone. In order to make the determination with respect to the applicable release limits we assumed that 12000 gallons of water was pumped out of the clean sump to the circ water discharge block. This is an extremely conservative value in that the we assumed one hour of continuous sump pump operation at the capacity of the pump @ 200 gpm.

After further review, a more realistic value of the amount of water discharged from the sump to the circ water discharge block would be @ 1000 gallons.

This is, in my opinion, still very conservative in that at no time during the spill had the water reached the sump enclosure. Operation personnel, in the area at the time of the

spill, have stated that the only source of contamination believed to have migrated to the sump was from the floor drains. It is our belief that the floor drain plugs, that are present to prevent the intrusion of contamination into the clean sump, were not water tight. The conservative 1000 gallons figure was based on the following.

1-The TBCCW clean sump pump timer readings have shown an average of @ 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> of operation per week over the past month.

2-Based on #1 above the TBCCW clean sump pumps operate @ 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> per day which. in turn correlate to 1 pump down per hour.

3-The sump volume is

@500 gal.

4-Since the event went on for @ 45 min. a conservative approach of 2 pump downs in the 45 min. would be appropriate.

5-The float system in the sump is set up to pump @ half-.of the tank volume or.@ 250 gallons.

In conclusion I would concur with your assumption to use 1000 gallons of radioactive water to calculate the liquid release values for the 8/14/92 liquid release.

EVRLUATION OF TBCCW SUMP RELEASE PATHWAY - 8/14/92 Calculations Assumptions The TBCCW sump pump is rated at 200 gpm.

The worst case scenario is that this sump ran for one hour while radioactive liquid from the backwash receiving tank was overflowing onto the floor and leaking into the sump.-

The one hour duration was based upon the fact that the SW rad monitýor alarm came in high at 1338 and the TBCCW clean sump was secured at 1430.

Chemistry technicians sampled the clean sump at 1410 and the TBCCW area floor at 1405.

Isotopic analyses of both the floor and the sump are attached.

A tritium analysis was performed on the sump sample and found to be 1.06E-5 uci/ml at 1410..

  • . 13Only 4euir radionuclides were identified in the 'clean sump(I-"

1311A 1-133, 1-134 and 1-135) probably due to the shorter count time of this sample.

Therefore, the floor sample data was used to extrapolate the probable concentrations of all identified radionuclides possible in'the sump sample.

This ratio was set at 600 to 1 based upon the worst case radioiodine r4tio.

MEMORANDUM VERMONT YANKEE -

VERNON To File Date October 14, 1992 From Deborah Voland Subject REVISION OF AUGUST 1992 DOSE CALCULATIONS Enclosed are 2 pages from the monthly dose calculations from August that have been revised.

The revision of the "Beta and Gamma Air Doses from Noble Gases - Turbine Building Ventilation" was due to a minor error caused by unfamiliarity in using the spreadsheet designed to perform the calculation when the doses were calculated by someone filling in for me when I was on vacation.

The other revision is the result of calculating values for Sr-89 and Sr-90 for the liquid release that occurred in August.

The values were derived from the LLD levels of the. Turbine Sump sample and the scaling factors typical in the associated waste stream.

pee. I-EV4LUATION OF TBCCW SUMP RELEASE PATHWAY -

8/14/92 Calculations Assumptions The TBCCW sump pump is rated at 200.;gpm.

The "worst'- case'.

scenario is that this sump ran for One hour while radioactive' liquid from the backwash receiving tank was overflowing-onto the floor and leaking into the sump.

U-.:

The one hour duration Was based upon the fact tat the"

'Sw rad monitor alarm came in high at 1338 and the. TBCCW clean sump was secured at 1430.-

" hemistry technicians sampled the clean sump at 1410 and the.

-TBCCW area floor at 1405.

Isotopic analyses of both the floor and the sump are attached.

  • A tritium analysis was performed on the sump sample and found to be 1.06E-5 uci/ml at 1410.:

Lo.nly fOeiky radionuclides, were identified in the clean sump(I-

.131, 1-133, 1-134 and 1-135) probabl due to the shorter count time of this sample.

Therefore, the floor sample *data was used. to extrapolate the probable concentrations of all.. identified radionuclides possible in the sump sample.

This ratiowas set at.

600 to 1 based upon the worst case radioiodine.ratio.

Overflow of Condensate Demineralizer Backwash Receiving Tank On August 14, 1992 at approximately 1330, while backwashing the B condensate demineralizer and transferring the contents to the condensate demineralizer backwash tank, the electric pump which transfers the water from the tank to radwaste failed, reyilt>. in the backwash receiving tank overflowing onto the floor. The water was radioactively contaminated and contained some resin material

-e floor in the vicinity of the tank was flo,'Y-.d to a depth of approximately 1-2 inches.

Samples taken in ý ::earby sump indicated the presence of..,z.ioctive Iodine and Tritium.

The sump purrqps are designed to cycle if required by level so it is possible that some contaminated water was discharged to the river by way of the service water system (10,000 gpm) and'then into the main circulating water system (360,000 gpm) before entering the Connecticut River.

The precise volume of contaminated water that may have been discharged to the river is estimated to be less than 15 gallons. Radiation monitors and samples at

irt (if discharge did r," record any evidence of radioactivity and remained normal durn.

The actual volume of radioactive water discharged is estimated to be three orders *.. magnitude below the bounding calculated values, or less than 15 gallons. Connecticut Rive: flowat the time of the incident was approximately 6000 cf-DJM.8/20/92 TrnT0l P S71

1992, "TB Clean.Sump"

" AS a*f0low up to our discussion concerning the appropriate fl67 pathway *for blowdown of condensed water from the Station Air S.

Compressor, I have evaluated the attached memo from Steve McAvoy

.'concerning the analysis of some of the input sources to the TB Clean..Sump.

I have 'concluded -that, given the

.. radion'iilides identified in the compressor blowdown sample, the only appropriate method for disposal of this water is to send it.to Radwaste.

The.

concentration of tritium and other nuclides 'exceeds, in this

sample, the lower limit - of. detection for. tritium, and the "statistically significant" levels of the other huclides.
